Abstract (en)

Polycarbonate resins are chain-terminated with a group selected from those of the formula: <CHEM> wherein R1, R2 and R3 are each independently selected from the group consisting of hydrogen, halogen, hydrocarbyl of from 1 to 12 carbon atoms, inclusive; and halogen-substituted hydrocarbyl of 1 to 12 carbon atoms, inclusive; R1 is attached to a ring carbon atom at one of the 4, 5 or 6 positions; and R2 and R3 when taken together represent the divalent moiety of formula: - CH = CH2 - CH2= CH - which effectively creates an additional fused aromatic ring structure. The resins exhibit a low plate-out when processed thermally.
